Besides the legalities of it all the reason it is VERY important NOT to discuss anything with your H about the proceedings are as follows:
You have NO CLUE what your H told his attny and chances are he did not tell the full truth about what he has been up to. My H failed to tell his attny he had been having an affair for 6 months and painted the picture to his attny that we simply decided we could not make our marriage work.
Attnys can only advise their client based on the information that is supplied. Once I received the paperwork, retained counsel and filed all my motions/petitions and responses my H's attny was a bit stunned with the information "my side" provided.
Chances are your H will hear what he likes from the attny and discard the rest. Your H will try and convince you that YOU are the one making this hard.
My H would see his attny and call or e-mail me to tell me what he said (so stupid, lol!). I would listen but know my attny was telling me something totally different. Listen but don't engage. Extract the facts as my attny used to say!
